Man: God, give me a perfect woman.
God: Granted.
**
M: God, please do something, she did not stay even for a minute, and where has she gone, I do not know.
G: I will grant a woman who stays with you for much longer time.
M: Ok.
**
M: O, God what have you given to me?
G: What happened?
M: She is not perfect, she has lot of problems.
G: That is the thing, the Heisenberg's uncertainty principle.
M: Oh, my god, I do not understand this principle.
G: The principle says: If you get the position of a particle very correctly and perfect, then its velocity and movement cannot be determined accurately; and if you can determine its velocity correctly, then its position cannot be ascertained accurately.
M: But, what the woman had to do with the principle?
God: I follow the principle.
Man: So, what does it really mean?
God: Read modern physics.
